IMPROVEMENT IN CORN-HUSKEBS.

Specification forming part of Letters Patent No. 135,840, dated February ll, 1873.

To all whom it may concern: Be it known that I, PETER PHILIP, of Stockport, in the county of Columbia and Statebf New York, have invented certain'nnprovements in Corn-Huskers, of which the following is a specification:

This invention relates to that class of cornhuskers constructed with a set of picking-rolls to piek the ears oft' the stalk, and one or more sets of husking-rolls which receive the ears from the picking-rolls and remove the husk. My improvement consists, lirst, in gearing the picking-rolls together at both ends by means ot spiral gears, the teeth of which are right-handed at onev end and left-handed at the other end of the roll. The rolls with such spiral gears are so arranged that anything entering between the gears will be fed toward the center ot the rolls, when they are turned in the proper direction. The result of this construction and arrangement of the pickingrolls is twofold. The tendency ot' the spiral gearing at one end of the rolls to move them anced by the opposite action oi' the gearing at the other end ot' the rolls; and the centerfeed of the gearings will keep the journals and bearings clean most eftectually. Second, in providing the grooved pickin g-rolls with one or more longitudinal ribsacross the grooves to insure the pinching oft' of the ears, and to prevent them from being drawn between the rolls. 'Grooves or depressions corresponding to the longitudinal ribs are formed in the respective rolls. Third, in preventing the endwise movement of the husking-rolls in respons'eto the action of the spiral gearing connecting them, by the use ot' a fixed collar upon one of the rolls, and a corresponding groove, entered 'by such collar, upon or in the other roll.

lt will be understood that the huskingrolls must permitthe unobstructed discharge of the ears at one end, so that the expedient described to prevent the endwise movement of the picking-rolls cannot be employed in connection with the husking-rolls.

Figure l is a plan view of a corn-husker showing my improvements. Fig. 2 is a vertical longitudinal section. Fig. 3 is an elevation of the pickin g-rolls detached.

The same letters of reference are used in all the iigures in the designation of identical usual, are, at their upper ends, geared together by the spiral gears G1 D1. The roll C is pro- Avided with a collar, G2, which runs in the groove D2 in the surface of the roll D, so that no opposite endwise movement ofthe respective rolls can take place in consequence of the action of the spiral gears. E refers to the spikes upon the roll C, and F to the spikes upon the roll D. The spikes are arranged in spiral rows, and annular grooves e and f are formed in the surface of the rolls to let the spikes pass, and to make the contact oi' the rolls, thus spiked, possible.

What I claim as my invention, and desire to secure by Letters Pat-ent, is

l. The picking-rolls A B geared together at both ends by spiral gears, the teeth of which run in contrary directions at opposite ends of the rolls, substantially as and for the purposes set forth.

2. The grooved picking-rolls A B having longitudinal ribs c and corresponding grooves or depressions c, substantially as and for the purpose specified.

3. The rolls C D geared together by spiral gears, in combination with the collar O2. and groove D2, substantially as and for the purpose specified.

In testimony whereof I have signed my name to the foregoing specication, in the presence ot two subscribing witnesses.

' PETER PHILIP.
